[Etiology of growth retardation in children of adolescent mothers].

The influence of some nutritional and hormonal factors in the growth failure detected in children of teenage mothers belonging to medium-low socioeconomic level (SEL) was studied. They were compared with children of mothers older than twenty years of the name SEL. Only growth retarded children of teenage mothers had significant delay in bone age, compared with chronological age (14.8 +/- 4.1 vs 18.2 +/- 2.2 months respectively). Children with growth failure had significantly lower plasma Zn (85.7 +/- 13.3 vs 94.6 +/- 17.9 micrograms/dl), Cu (106.2 +/- 32.5 vs 122.0 +/- 13.8 micrograms/dl) and hemoglobin (Hb) (11.7 +/- 2.1 vs 12.8 +/- 2.1 micrograms/dl) levels. No differences in plasmatic levels of thyrotropin, thyroid hormones and response of growth hormone to L-Dopa stimulation were detected in comparison with those of children with normal stature. We concluded that etiological factors of growth failure were similar in children of teenage and adult mothers according to the parameters analyzed. The increased prevalence of growth failure in children of teenage mothers may be due to a greater impact of the analyzed factors.

[Hypogonadotrophic hypogonadism and anosmia: Kallman's syndrome].

Three male adolescents with hypogonadotropic hypogonadism and anosmia (Kallmann Syndrome) and treated with testosterone enantate are presented. The type of inheritance, the importance of others clinical signs and symptoms in an early diagnosis, variations in the response of gonadotropins and prolactin to LHRH and chlorpromazine. The optimal treatment schedule with testosterone for these patients seems to be intramuscular testosterone enantate 200 mg at two weeks intervals. Longer intervals produce less satisfactory responses.

A three-year evaluation of four commercial equine influenza vaccines in ponies maintained in isolation.

Ponies held in isolation for 40 months were vaccinated and revaccinated with four commercial equine influenza vaccines. Little or no HI antibody was detected after the first inoculation; second and subsequent annual revaccinations produced peak HI antibody titres between 7 and 14 days. Titres fell quickly between 14 and 28 days and less quickly thereafter. The decline of HI antibody appeared to be related more to the initial titre attained and to the period after vaccination than to the composition of the vaccine. The response to a first annual revaccination was superior to that produced by a second annual revaccination. Ether-treated antigens were required to identify primary and secondary responses to the equine-2-component of vaccines.

Field observations on influenza vaccination among horses in Britain, 1971-1976.

The observations reported in this paper were obtained as part of a long term surveillance programme designed to monitor the efficacy of influenza vaccines and study the prevalence of influenza and other respiratory viruses among horses in Britain. Inactivated influenza vaccines were found to be effective in protecting horses from disease caused by influenza A/equine-1 but were less successful in protecting horses against influenza A/equine-2. The paper presents the clinical, epidemiological virological and serological findings obtained between 1971 and 1976.
